MACHINE FOR USE IN CONSTRUCTING AND REPAIRING BOWLlNG-ALLEYS.

SPECIFICATION forming part of Letters Patent No. 758,424, dated April 26, 1904.

Application filed April 11, 1903. Serial No. 152,205. (No model.)

New York, have invented certain new and useful Improvements in Machines forUse in Constructing and Repairing Bowling-.Alleys, ofv

which the following is a specification, such as willenable those skilled in ,theart to which it appertains to makeanduse'the same.

The object of this invention is to provide,

an improved machine or apparatus for use in constructing and repairing. bowling-alleys, and particularly for planing, smoothing, and polishing such alleys in the construction thereof, and for cleaning and polishing alleys when necessary, and for repairing old alleys when they have become irregular or out of true in use or replaning the same so as to renden them regular and true, and also smoothing and polishing the same; and'with this and other objects in View the invention consists in a machine or apparatus of the class specified constructed as hereinafter described and claimed. 7

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a plan viewof a part of a bowl-' ing-alley with my improved machine in position for use, the machine being also shown in plan; Fig. 2, a side elevation of the construction shown in Fig. 1, part of the alley being in section; Fig. 3, a transverse section thereof; Fig. 4, a side elevation of one form of a smoothing or polishing roller which I employ, and Fig. 5 a perspective view of one form of a planer which I employ. Fig 6 is a detail sectional view illustrating the means employed for regulating the height of the tracks or ways.

In the drawings formingpart of'this specification I have shown an ordinary bowlingalley comprising a hallway a, at the opposite sides of which are the usual gutters a and in the practice of my invention I provide a mawith wheels d, preferably in'theforrn of or- 'dinary car-wheels and adapted to travel on temporary tracks or ways 6, placed in the gutters .Over the rear axle o is placed a frame 5 at one side of said seat are keepers g, arranged transversely of said platform or truck-frame, within which is placed a brakeshaft h, provided at its inner end with an upwardly-directed crank or handle k adapted to be operated by a person sitting on the seat f, and said shaft h is provided at its outer end with an arm which carries a brakeshoe 7:, adapted to bear on the perimeter of the adjacent wheel d.

Arranged in front of the seat f is an electric or other suitable motor 2', having a powershaft '6 which passes transversely therethrough and the opposite ends of which are provided with sprocket-wheels 41 and the platform or truck-frame b is provided in front of the motor 2' with a transverse raised portion 6 in which are placed vertically-adjustable supports 70. The vertical adjustable supports 76 preferably consist of screw-threaded members which pass upwardly throughbearings 70 secured to the part if of the platform or truck-frame Z), and the upper ends of which are provided with screw-threaded wheels or members m, and secured to the top of the part b of the platform or truck-frame is a transverse member 11, the ends of which are raised and extend over the wheels or members m, as shown at M, and the upper ends of the supports in pass therethrough,and by turning the wheels or members m the supports k may be vertically adjusted, as will be readily understood.

In practice I mount in the lower ends of the supports 70 a cylindrical planer 0, (shown'in Fig. 5,) or polishing-roller 0 (shown in Figs. 2 and 4,) or an emery or sandpaper roller 0 (shown in Fig. 3,) and in practice the planer, polisher, or sandpaper or emery roller are provided attheir opposite ends with sprocket- ,seat f, and secured to the platform or'truckwheels 0, which are geared in connection with the wheels of the motor-shaft by drivechains 0".

It will be understood that the nature of the work to be done will determine which of the devices 0 or 0 is to be used, and the size of the wheels 0 and 0 may be regulated so as to give the planer, polisher, or other device used any desired speed. It will also be understood that the alleys are constructed in the usual manner, and when new alleys are being formed the planer 0 is first used, after which the emery or sandpaper roller 0 is used and then the polisher 0 and this order may be followed when the alleys are out of true or uneven and need substantial repairing; but when all that is necessary is to clean and polish the ballway of the alley the polisher 0 may be used, or a sandpaper roller may first be used, after which the polisher may be used. I also preferably place over the front axle 0 a box or other suitable receptacle 7, which is filled with bricks, weights, or other suitable material, so as to give weight to the machine or apparatus, and the said machine or apparatus may be pulled or pushed over the tracks 6, or a low-gear motor may be employed, my invention being not limited to any means for moving the truck-frame over the tracks 6. It will be understood that if the truck be moved over the tracks 6 by hand the seat and brake will not be necessary, and it will further be understood that as the machine or apparatus is moved forwardly over the tracks 0 the motor is put in operation and the planer, polisher, or other device used is rapidly revolved on the surface of the ballway, and the required work is thus quickly and easily performed.

In order to adjust the height of the tracks or ways a, the device shown in Fig. 6 may be employed, and referring thereto, 8 designates a compound screw, one end of which is provided witha coarse threads, similar to the lagscrew ordinarily employed, while the other end is provided with a fine thread .9 a shoulder 8 being arranged between the threads 8' and s to provide for the application of a wrench. Mounted upon the upper end of the screw 8 and engaging the thread 8 is a support s, one end of which is provided with an upwardlyextending flange s and fitted in said flange s is a securing-screw s, designed to engage the track or way a, which in practice is mounted upon the support s and rests against said flange. It will thus be seen that after the tracks or ways a are placed in position in the gutters (L2 the height of the same may be regulated by simply rotating the screw 8 through the medium of a wrench applied to the shoulder 8 and, on the other hand, the height of said tracks or ways when installing the latter in the gutters a may be determined by first adjusting the support 8 upon the upper end of the screw 8, and then by introducing the latter into the bottom of the gutter until the shoulder 8 contacts with the bottom of the gutter the support 8* assumes the position at the predetermined height.

While the planer 0 and the other tools designed to be substituted therefor are illustrated in the drawings as extending directly transverse of the truck or frame, it will of course be understood that this planer and the other tools may be arranged at an angle of approximately forty-five degrees, or diagonally of the truck or frame, the relation of the motor, its shaft, and the gearing being such as to properly operate the planer or the othertools when placed in the angular position stated. Under such arrangement of the planer a shear cut will be effected, and consequently there is absolutely no liability of the tool in its operation upon the ballway tearing the latter or defacing the same in any degree.

Any suitable truck-frame may be employed, and various changes in and modifications of the construction herein described may be made without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, What I claim as new, and desire to secure by Letters Patent, is

The herein-described apparatus for use in constructing and repairing bowlingalleys, consisting of a truck-frame provided at its opposite ends with axles having wheels adapted to travel on tracks or ways placed in the gutters, said frame being also provided with a central transverse raised portion, vertical tubular bearings mounted in said raised portion, adjustable supports mounted in said bearings transversely of the truck-frame, a planer mounted in said supports, and a motor mounted on the truck-frame and geared in connection with the planer, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 11th day of April, 1903.

JOSEPH F. DARRELL.
